1 Application filed November 24, 1911. Serial No. 662,092.

Toallwkom it may concern:

' Be it known that I, CALDER C. .GIBSON, a

citizen of the United States,--residing at.

Bufialm-in the county of Erie and State of New York, have invented certain new and useful Improvementsin Cutting and Stamping Machines, .of which the following. is 2.

' T of the printing stamps to show the inte'rior specification.

This invention relates to that class known as cutting'and stamping machines in which a portion of a bill, coupon, invoice, or-other 3 paper is completely severed or cut off, and

at the same time a date and other particulars or records are printed on each portion. 1 One of the features of the invention has;

reference to the novel arrangement of a knife or other cutting implement in the path of the operating-handle of the printing; stamp, so that the knife or other cutting implement will be moved to sever a portion off a paper at the same time that the printing stamp is moved to print certain particulars:

thereon.

Another feature of the invention has reference to the removable attachment of the printing stamp to its operating handle, so

that the stamp may be detached and another substituted, or the date ,or other :)articu1ars thereon may be changed.

The principal object of the invention is to provide a simple, quick and convenient machine which will simultaneously printand cut coupons, bills, invoices, or other papers, such as for instance gas blllS m which a small stub is printed at one side of the bill proper and is adapted to be severed at the same time that the bill is stamped.

The invention also relates to certain details of construct-ion which will be hereinafter described and claimed, reference being had to the accompanying drawings in which:

Figure 1 represents a side elevation of the improved. machine showing the knife and printing stamp in their non-cutting and non-printing position in full lines and in cutting and printing position in dotted lines. Fig. 2 is a top plan view of the improved machine. Fig. 3 is a detached front view of the printing stamps and their supporting frame, also showing one of the hinged sup-v porting bottom pieces partially open in dotted lines. Fig. 4: is a vertical section through the printing stamp-supporting frame on line aa, Fig. 3. Fig. 5 is a vertical longitudinal section through the printing stamp-supporting frame. Fig. 6

enlarged detached View of the cutting knife and its complementary stationaryv blade. Fig. 9 is a fragmentary section through one construct-ion of the same.

In referring to the preferred adaptation Patented Sept. 17, 19 12.

of the machine shown in the accompanying v drawings in detaillike numerals designate In the adaptation shown the printing and cutting mechanisms are mounted on a box which is constructed with a slot for the pascoupons or other papers drop into the interior of the box. p l

Referring to Figs. 1 and 2, the box is composed of a bottom-1, ends 2, and atop 'sage of the cutting knife and an opening 1' through which the severed port-ions of the 4, and the front of said box is provided with an opening in which a drawer 5 is slidably mounted, as shown in Fig. 1.

a An ink pad 6 is arranged on the rear portion of the top of the box and a longitudinal slot 7 is cut in the box top in front of r thefink pad for the passage of a cutting knife as will be more specifically described farther on. a

A stationary cutting blade 8 is fastened rigidly to one of the, side walls of the slot 7 by screws 9 and a movable cutting blade or knife 10' forming the movable cutting implement is pivoted to one side of the 'stationary blade toa laterally raised or. 'elevated portion of the rear end thereof by a bolt 11, as shown in Figs. 1, 2, and 8.

It will be noted by referring to Fig. 8 that the pivotaLbolt 11 is located in a plane sufliciently above the horizontal plane of the cutting edge of the stationary blade 8to roduce an extremely acute shearing angle, in fact the two o'pposedcutting edges are almost parallel when in cutting position. The great advantage of this is that the cutting operation does not have a tendency to force the article being cut laterally out from beneath the movablecutting knife.

'The movable cutting member, blade or knife 10, is normally maintained in an elevated non-cutting position by a spring 12, as shown in dotted lines in Fig. 1, the spring being attached at its upper end to the rear end of the cutting blade or knife, and at its lower end to an-eye 13'fastenedto-the bet the box, as shown'in-dotted toin, of accompanyingdrawings; I The spring does not e'- 'nd' vertically g-downward, but at an outward angle-diagonally toward the box corner so that the tend-.5

ency ofthe spring is not only to maintain the cutting blade normally in anon-cutting position, but also to exert suificient lateral pull m to keep he edge of the. movable cutting blade m'clo'se contact with; the stationary blade, so thata keen, quick'andpositive cuttin eifectis rodueed. I Y

a he printm mechanism is mounted above the box ingl sup'ported by a metal frame which is attached to .thebox by: screws 14 and projects'abovethe top thereof. This metal frame is composed of two sidemembei 's15 and 16 and an end 17, asi shown in Figs. 1 and2, "and also forms an 'inclosing;; frame for the ink pad .6.

The slde frame members .15 and 16 are? each provided with forwardly and upwardly 7 extending enlargements 18 to the front cor- E ners of whichthe ends of a U-shaped operating lever 19 is pivoted by pins 20, as shown inFigs.1and2. 1

The U-sha edlever dinal portionsof the the central hand-graspingv portion 21 in which the printing stamps are removably mounted. v p The. construction. of this stamp supporting frame will be understood by referr ng to .Figs. 1, 2,3, 4, and 5, the frame being ofrectangular form and havin arectangular opening in which a metal ished shell 23,.

4 also of rectangular form and attached to the boxes 24 containing the rinting" stamps by screws 25, is removably fitted.

The frame 22 is provided with'two upwardly extending vertical end ears 26 I 5 through theupper portions of which 'piv oting pintles'*27- are inserted to pivot the frame to the U-shaped lever. Bosses, or enlargements, 28, are formed near the middle of the longitudinal portions of the U-shaped lever through which the p'intles 27 are fitted,

as shown in Figs. 1 and 2.

The shell. 23 together with stamps ,are' fastened 1 in g bar", 29 constru the printing 7 v ted as shown in Fig. 6 and having: an enlarged knurledknob 30 at one end forming aconvenient finger-grasping-portion and anintermediate, reduced portion, '31. v

The locking bar 29 is adapted to be fitted so through openings in the end ears and a hori zontal opening 1n a'vertical tubular portion 32 extending up from the shell 23 and to be fastened'in place in said horizontal opening by a spring-pressed slide 33fitted in a ver-.. 5 tical opening 34 in the portion 32,,as shown is provided withja centralI han -grasping portion 21 and al' 0 frame 22 is extended between the longitu-j U-shaped lever below sion of the bloc in the frame by a lock in Fig. 4 an enlarged projecting I knurled upper'end and a dependmglower end "adapted to engage in the groove of the reduced portion'3l', as shown in Fig.4. The vertical tubular portion 32 has its lower end The block 5 is provided with a depending portion 36 which is adapted to cont-actv withthe top of the movablecutting member or knife. andmove it downward as the U- sai plate or piece rollers'3 9 and 40v located within the box and having a series -of projecting type bars 41.

'The bottom plate '37" is provided with a slot 42 through which one of the-type bars fitswhen the plate is closed against the'box, as shown in Fig. 9. It will be noted by referring to Fig. 8 that being adapted to open downwardly, as shownv 1n dotted lines in Fig. 3.. and a rubber band 38 mounted on the cutting knife is pivoted to the stationary,

blade at a point above the horizontal plane of the cuttmg'edge of the said stationary blade.

angle between" .the cutting edges of the blades is so acute that the paperis out easily, quickly and evenly without in any way movg or disturbing the position of the paper sheet on the't op of the box.

.I claim: v r I 1. In a machine of the class described, thecombination with a main frame, of printing mechanism pivotally linked to sald. main frame and mcluding a. stamp supporting frame, a block fitted in-the stamp supporting frame and having a vertical extenslon provided with a vertical opening and a trans verse opening intersecting the vertical open-- ing, a locking bar slidablymounted' in the stamp, supporting frame and' 4 v a the transverse opening infthe vertical extenand a spring slide in the vertical openingof the vertical extension.
